Finding packages:
How do you find the package that's got the feature you're looking for? First, do

sudo apt-get update

so your package list is up-to-date, and then try something like

sudo apt-cache search tunnelsudo apt-cache search 'php.*'

That is how you tell apt to search the packages using REGEX (regular expression, a pattern-matching 'language') -- if your pattern uses any keystrokes that mean something to your command shell (e.g. [|?*] ) you'll need to quote them so that apt-cache will be able to see them, instead of having the shell expand the term to a list of file names that mean something else entirely.

PuTTY is the most popular SSH client for Windows. One, and probably the only one, of PuTTY drawbacks is that you need to start a new copy of PuTTY every time you open a new connection. So if you need e.g. 5 active connections you run 5 PuTTY instances and you have 5 PuTTY windows on the desktop.

MTPuTTY (Multi-Tabbed PuTTY) is a small *FREE* utility enabling you to wrap unlimited number of PuTTY applications in one tabbed GUI interface. You are still continue using your favorite SSH client, but you are no longer messing around with PuTTY windows - each window will be opened in a separate tab.

Last.fm is a UK-based Internet radio and music community website, founded in 2002. It claims over 30 million active users based in more than 200 countries.

Using a music recommender system called "Audioscrobbler", Last.fm builds a detailed profile of each user's musical taste by recording details of all the songs the user listens to, either on the streamed radio stations, the user's computer or some portable music devices. This information is transferred to Last.fm's database ("scrobbled") via a plug in installed into the user's music player. The profile data is then displayed on the user's profile page. The site offers numerous social networking features and can recommend and play artists similar to the user's favorites.

shell-fm is a lightweight, console-based player for Last.FM radio streams. It’s pretty small (the binary is currently about 70K, or about 60K when stripped) and it has most features the official player has, if not even a few more. Additional features are, for example:

The all-time top post of linuxpoison is - List of best Linux blogs but there are lots of blogs in this list which are dead or non-functional, so I am thinking for building the new list of blogs dedicated to linux or/and open source ONLY.

I will put this list on the separate blog page for easy accessibility.

The purpose of application profiling is to check whether an application, which is being developed, works as it is supposed to and to assist the developers in improving the application.

Profiling Prerequisites:
Profiling an application involves the following steps:
* Profiling applications on remote hosts requires the installation of the Agent Controller. Profiling local applications requires no additional install or setup.
* Launching an application
* Specifying profiling criteria
* Using profiling views to analyze data
* Save profiling data or resources if you expect to use them again

Perf is a profiler tool for Linux 2.6+ based systems that abstracts away CPU hardware differences in Linux performance measurements and presents a simple command-line interface. Perf is based on the perf_events interface exported by recent versions of the Linux kernel.

OGMRip rips and encodes DVD into very high quality AVI, OGM, MP4, or Matroska files. It supports a wide variety of video (XviD, Lavc, X264 and Ogg Theora) and audio (Ogg Vorbis, MP3, PCM, AC3, DTS and AAC) codecs and can extract SRT or VobSub subtitles. OGMRip tries as much as possible to automate most of the steps of the encoding: it computes the video bitrate for a given output file size, auto detects cropping and scaling parameters, ... It also allows to embed multiple audio and subtitle streams in a single file and to encode only a few chapters of a DVD title..

It's been nearly twenty years since Linus Torvalds let loose Linux on an unsuspecting world, and on July 22 he finally updated the open source OS kernel to version 3.0.

Total Torvalds has integrated over 9,800 changes to Linux 3.0, the last of which 2200 were mainly corrections. As is usually two thirds of all new or updated driver changes.

Summary:
Besides a new version numbering scheme, Linux 3.0 also has several new features: Btrfs data scrubbing and automatic defragmentation, XEN Dom0 support, unprivileged ICMP_ECHO, wake on WLAN, Berkeley Packet Filter JIT filtering, a memcached-like system for the page cache, a sendmmsg() syscall that batches sendmsg() calls and setns(), a syscall that allows better handling of light virtualization systems such as containers. New hardware support has been added: for example, Microsoft Kinect, AMD Llano Fusion APUs, Intel iwlwifi 105 and 135, Intel C600 serial-attached-scsi controller, Ralink RT5370 USB, several Realtek RTL81xx devices or the Apple iSight webcam. Many other drivers and small improvements have been added.
